Insider behavior matters because research based on real-time signals has
shown that a properly modeled picture of insider actions can provide the most
accurate reflection of the prospects for the company, industry, economic sector,
or even the stock market in general, going forward.

This makes perfect sense from an intuitive perspective. Corporate insiders
possess all the necessary skills and characteristics that one could use to
describe the "successful" investor. These include: A deep knowledge and
understanding of the company and/or industry; A demonstrated ability to produce
success; The training necessary to understand risk and to control it; The
wherewithal (capital) to take advantage of opportunity when it presents itself
and finally; A tendency to go against the crowd.

In general, insider buys are more useful. Since insiders have exclusive
information on the company performance, if they are risking their own money on
the stock, usually they should have good reasons, especially when several
insiders buy the stock at the same time.

Below are some sample insider trades:
